Description

Die Erfindung betrifft eine Belastungsüberwachungsvorrichtung für Trittbretter gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a load monitoring device for running boards according to the preamble of claim 1.

Am Heck der Müllfahrzeuge sind ausklappbare Trittbretter angeordnet, auf denen die Müllwerker während der Vorwärtsfahrt stehen können. Das Müllfahrzeug darf allerdings dann nicht zurückgesetzt werden, wenn die Müllwerker auf den Trittbrettern stehen. Es ist daher bereits bekannt, Trittbrett-Sensoren vorzusehen, die beispielsweise mit dem Rückwärtsgang des Müllfahrzeugs gekoppelt sind und eine Blockierung der Rückwärtsfahrt bewirken, wenn die Trittbretter belastet sind.Fold-out footboards are arranged at the rear of the garbage trucks which the garbage collectors can stand while driving forward. The However, refuse collection vehicles may not be reset if the Garbage workers stand on the running boards. It is therefore already known Provide running board sensors, for example, with the reverse gear of the Garbage truck are coupled and blocking the reverse drive effect when the running boards are loaded.

Aus der DE 41 21 720 A1 ist ein Müllfahrzeug bekannt, bei dem die Trittbretter mit Kontaktschaltern ausgerüstet sind. Um rückwärts bzw. über eine bestimmte Grenzgeschwindigkeit hinaus vorwärts fahren zu können, müssen die Trittbretter in eine nicht mehr benutzbare Position geschwenkt werden. Wenn dies nicht erfolgt, wird automatisch über ein Pneumatikventil die Bremse des Fahrzeugs oder eine Gangsperre aktiviert und das Müllfahrzeug kann nicht bewegt werden bzw. es wird abgebremst. Die Aktivierung des Pneumatikventils erfolgt über ein Relais, welches einerseits über den an den Trittbrettern zwischen Trägerarm und klapp- bzw. schwenkbarem Auftritt fest angeordneten Kontaktschaltern angesteuert wird und im stromlosen Zustand eine Verbindung zwischen Rückfahrlichtschalter und Pneumatikventil herstellt. Der Kontaktschalter soll zwar manipulationssicher sein, nicht jedoch das Trittbrett. Es kann daher nicht ausgeschlossen werden, daß das Trittbrett von den Müllwerkern so entlastet wird, daß beim Aufsteigen diese Kontaktschalter nicht betätigt werden. Es sind dann auch Fahrten auf dem Trittbrett möglich, die aufgrund der Sicherheitseinrichtung nicht möglich sein dürften.A refuse vehicle is known from DE 41 21 720 A1, in which the Running boards are equipped with contact switches. To backwards or over to be able to drive forward beyond a certain limit speed the running boards must be swiveled into a position that is no longer usable become. If this is not done, a pneumatic valve automatically the vehicle's brake or a gear lock is activated and the garbage truck cannot be moved or it is braked. Activation of the Pneumatic valve takes place via a relay, which on the one hand via the to the Footboards between the support arm and the foldable or swiveling tread arranged contact switches is controlled and in the de-energized state creates a connection between the reversing light switch and the pneumatic valve. The contact switch should be tamper-proof, but not that Footboard. It can therefore not be excluded that the running board of the garbage collectors are relieved so that this contact switch when climbing not be operated. Rides on the running board are then also possible, which should not be possible due to the safety device.

Aus der DE 39 18 971 C2 ist ein Müllfahrzeug mit einer Drehzahlbegrenzungseinrichtung bekannt, die beim Besteigen des zweischalig ausgebildeten Trittbrettes durch einen Müllwerker über einen Kontakt automatisch aktiviert wird. Hierzu sind an den Trittbrettschalen beispielsweise Näherungsschalter vorgesehen, die jedoch auf einfache Weise manipuliert werden können. Eine andere Ausführung sieht Handgriffe vor, die bei Berührung ebenfalls ein Signal abgeben. Auch hier kann beispielsweise von den Müllwerkern eine Isolierung angebracht werden, um die Signalabgabe zu unterbinden.From DE 39 18 971 C2 is a garbage truck with a Speed limiting device known when climbing the double-shell trained footboards by a garbage collector via a contact is activated automatically. For this purpose, for example, are on the running board shells Proximity switch provided, but manipulated in a simple manner can be. Another version provides handles that at Touch also give a signal. Here too, for example insulation is installed in the garbage collectors to prevent the signal from being emitted prevention.

Aus der DE-OS 37 29 107 C2 ist ein Abfallsammelfahrzeug mit Trittbrettern bekannt, die bei Auflast einen Kontaktschalter auslösen, der beispielsweise als Lastschalter ausgebildet ist und die Rückfahrleuchte mit einem Relais verbindet. Dieses Relais bewirkt bei Auflast und Rückwärtsfahrt einen Motorstopp, der erst dann aufgehoben wird, wenn die Auflast auf dem Trittbrett entfernt worden ist.From DE-OS 37 29 107 C2 is a refuse collection vehicle with running boards known that trigger a contact switch when loaded, for example as Load switch is formed and the reversing light with a relay combines. This relay causes a load and reverse Engine stop, which is only released when the load on the Running board has been removed.

Die DE-OS 25 47 959 beschreibt eine lastabhängige Schaltvorrichtung, die insbesondere zum Absichern beweglicher Trittstufen an Fahrzeugen vorgesehen ist.DE-OS 25 47 959 describes a load-dependent switching device that In particular, intended to secure movable steps on vehicles is.

Sämtliche bekannten Trittbrettüberwachungseinrichtungen können so manipuliert werden, daß die Sicherheitsfunktion außer Kraft gesetzt wird und eine Rückwärtsfahrt des Müllfahrzeugs auch dann möglich ist, wenn die Müllwerker auf dem Trittbrett stehen. All known footboard monitoring devices can do so manipulated to override the security function and a reverse drive of the garbage truck is also possible if the Garbage workers stand on the running board.

Es ist daher Aufgabe der Erfindung, eine Belastungsüberwachungsvorrichtung für Trittbretter zu schaffen, mit der eine Trittbrettbelastung durch einen auf dem Trittbrett stehenden Müllwerker auch dann noch erkannt wird, wenn das Trittbrett durch eine Manipulation weitgehend entlastet sein sollte.It is therefore an object of the invention to provide a load monitoring device for running boards with which a running board load caused by one garbage worker standing on the running board is recognized even if that Footboard should be largely relieved by manipulation.

Die Aufgabe wird dadurch gelöst, daß die Belastungserkennungseinrichtung Sensoren zum Erkennen von Bewegungen des Trittbrettes und/oder der Haltemittel in mindestens zwei Raum-Richtungen aufweist.The object is achieved in that the load detection device Sensors for detecting movements of the running board and / or the Holding means in at least two spatial directions.

Der erfindungsgemäßen Lösung liegt die Erkenntnis zugrunde, daß die Belastungserkennungseinrichtung nicht nur in einer Bewegungsrichtung, nämlich der Belastungsrichtung beim Betreten des Trittbrettes, sondern auch in mindestens einer weiteren Bewegungsrichtung sensitiv sein muß, um die Belastung des Trittbrettes trotz Manipulationen erkennen zu können.The solution according to the invention is based on the knowledge that the Load detection device not only in one direction of movement, namely the direction of loading when entering the footboard, but also in at least one other direction of movement must be sensitive to the To be able to recognize the load on the running board despite manipulations.

Bei einer beispielsweise manipulativen Entlastung des Trittbretts, wie Hochbinden etc., werden beim Betreten des Trittbretts durch den Müllwerker nach wie vor Kräfte auf das Trittbrett und/oder die Haltemittel ausgeübt, die zu einer Bewegung und/oder einer Verformung der Bauteile führen. Die Bewegung in vertikaler Richtung nach unten wird durch die Manipulation möglicherweise erheblich reduziert sein. Stattdessen werden verstärkt Biegemomente auftreten, die mit einem oder weiteren Sensoren erfaßt werden können.With, for example, manipulative relief of the running board, such as Tie up, etc., when entering the footboard by the garbage collector forces are still exerted on the running board and / or the holding means lead to movement and / or deformation of the components. The Movement down in the vertical direction is caused by the manipulation may be significantly reduced. Instead, be reinforced Bending moments occur which are detected with one or more sensors can.

Vorzugsweise weist die Belastungserkennungseinrichtung Sensoren zum Erkennen wenigstens eines Biegemoments und mindestens einer vertikalen Bewegung auf. Da mit solchen Manipulationen nur geringfügige Bewegungen und geringe Kräfte verbunden sind, muß die Belastungserkennungseinrichtung entsprechend empfindlich ausgebildet sein. The load detection device preferably has sensors Detect at least one bending moment and at least one vertical one Movement on. Because with such manipulations only slight movements and low forces are connected, the load detection device be appropriately sensitive.

Um eine weitere Verbesserung im Sinne einer umfassenderen Überwachung des Trittbrettes zu erzielen, werden von den Sensoren vorzugsweise nicht nur lineare, sondern auch Kipp- oder Drehbewegungen erfaßt. Die optimale Überwachung des Trittbrettes kann dadurch erreicht werden, daß Sensoren zur Überwachung aller möglichen sechs Freiheitsgrade eingesetzt werden, so daß z.B. auch Rotationsbewegungen des Trittbrettes erkannt werden. Hierfür ist es nicht zwingend erforderlich, daß die Aufhängung des Trittbrettes eine Bewegung in all diesen Raumrichtungen zuläßt. Durch Manipulation werden die Bewegungen des Trittbretts unter Belastung verändert, so daß nicht nur zusätzliche Biegekräfte, sondern Bewegungen in horizontaler Richtung oder Drehbewegungen auftreten können, die sich vorwiegend auf die Haltemittel des Trittbretts übertragen. Art und Anzahl der Sensoren sowie deren Ort der Anbringung richten sich nach der Bauart des Trittbretts und deren Befestigung.To further improve in terms of more comprehensive monitoring to achieve the running board are not only preferred by the sensors linear, but also tilting or rotating movements detected. The optimal one Monitoring of the running board can be achieved in that sensors for Monitoring of all possible six degrees of freedom can be used so that e.g. rotational movements of the running board can also be detected. It is for that not absolutely necessary that the suspension of the running board is a Allows movement in all these spatial directions. By manipulation the movements of the running board under load changed so that not only additional bending forces, but movements in the horizontal direction or Rotational movements can occur, which mainly affect the holding device of the Transfer footboards. Type and number of sensors and their location Attachment depend on the design of the running board and its attachment.

Vorteilhafterweise werden die Sensoren am Haltemittel des Trittbrettes angeordnet. Am empfindlichsten ist der Bereich des Haltemittels, der benachbart zum Befestigungspunkt der Haltemittel am Fahrzeug angeordnet ist.The sensors are advantageously on the holding means of the running board arranged. The most sensitive area is the area of the holding device, the is arranged adjacent to the attachment point of the holding means on the vehicle.

Vorzugsweise sind die Sensoren Dehnungsmeßstreifen, die bereits geringe Längendehnungen des Bauteils erkennen, an denen sie befestigt sind. Die Anordnung der Dehnungsmeßstreifen am Haltemittel des Trittbrettes ist so zu wählen, daß die Raumrichtungen, in denen das Trittbrett bewegt, belastet oder verformt werden kann, erkannt werden.The sensors are preferably strain gauges, which are already low Recognize the elongations of the component to which they are attached. The The arrangement of the strain gauges on the holding means of the running board is so too choose that the spatial directions in which the running board moves are loaded or can be deformed, recognized.

Vorzugsweise sind vier Dehnungsstreifen in einer Sensoreinrichtung, die auch als Meßdose bezeichnet wird, zusammengefaßt. Vorteilhafterweise kann diese Sensoreinrichtung seitlich in den Tragarm des Trittbretts eingesetzt sein.There are preferably four stretch marks in one sensor device, which too is referred to as a load cell. This can advantageously Sensor device can be inserted laterally into the support arm of the running board.

Vorzugsweise ist die Sensoreinrichtung mit den Dehnungsmeßstreifen in eine an sich bekannte Wheatstone'sche Brückenschaltung integriert, um bereits geringe Widerstandsänderungen der Dehnungsmeßstreifen zu detektieren. Die Wheatstone'sche Brückenschaltung kann als Halb- oder Vollbrücke ausgebildet sein, je nachdem, ob zwei oder vier Dehnungsmeßstreifen an die Wheatstone'sche Brücke angeschlossen sind. Eine Vollbrücke hat den Vorteil, daß auch eine Temperaturkompensation vorgenommen werden kann, so daß Fehlinterpretationen über die Belastung des Trittbrettes vermieden werden.Preferably, the sensor device with the strain gauges is in one known Wheatstone bridge circuit integrated to already to detect small changes in resistance of the strain gauges. The Wheatstone bridge circuit can be designed as a half or full bridge depending on whether two or four strain gauges are attached to the Wheatstone bridge are connected. A full bridge has the advantage that temperature compensation can also be carried out so that Misinterpretations about the load on the running board can be avoided.

Eine andere Ausführungsform sieht Druckschalter vor, wobei für jede zu erfassende Bewegungsrichtung ein eigener Druckschalter vorzugsweise am Haltemittel anzubringen ist.Another embodiment provides pressure switches, whereby for each direction of movement, a separate pressure switch preferably on Attachment must be attached.

Vorzugsweise umfaßt die Belastungserkennungseinrichtung eine Steuereinrichtung, die einerseits mit den Sensoren und andererseits mit den Fahrzeugkomponenten verbunden ist, um auf diese Weise beim Erkennen einer Belastung des Trittbretts auf das Fahrzeug einwirken zu können. Dies kann beispielsweise dadurch geschehen, daß im Führerhaus eine Anzeige akustischer oder optischer Art aktiviert wird. Die Steuereinrichtung kann beispielsweise Einfluß auf die Fahrtgeschwindigkeit oder auf Vorwärts- oder Rückwärtsgang nehmen, um so eine Gefährdung des auf dem Trittbrett befindlichen Bedienungspersonals zu verhindern. Welche Fahrzeugkomponenten mit der Steuereinrichtung verbunden sind, richtet sich nach den Anforderungen, die der Betreiber stellt. So kann die Steuereinrichtung auch mit dem Preßwerk des Sammelbehälters and/oder der Schüttung verbunden sein. Vorzugsweise werden bei Belastung des Trittbretts das Preßwerk und/oder die Schüttung angehalten oder abgeschaltet und/oder vor dem Anhalten oder Abschalten in eine sichere Stellung gefahren. Eine sichere Stellung für die Schüttung ist z.B. die Weiterfahrhöhe, d.h. eine angehobene Stellung, in der ein gefahrloses Weiterfahren möglich ist.The load detection device preferably comprises a Control device, on the one hand with the sensors and on the other hand with the Vehicle components is connected in this way when detecting a The impact of the footboard on the vehicle. This can happen, for example, that an acoustic signal in the cab or optical type is activated. The control device can, for example Influence on driving speed or on forward or reverse gear so as to endanger what is on the running board To prevent operators. Which vehicle components with the Control device depends on the requirements of the Operator provides. So the control device with the press of the Collection container and / or the bed connected. Preferably are the press and / or the bed when the footboard is loaded stopped or turned off and / or before stopping or turning off drove to a safe position. A safe position for the filling is e.g. the travel height, i.e. a raised position in which a safe Driving on is possible.

Vorzugsweise ist die Steuereinrichtung auch zur Aufnahme und Verarbeitung der Fahrzeugdaten ausgelegt. So kann z.B. die Fahrzeuggeschwindigkeit in die Auswertung der Meßsignale der Sensoren einbezogen werden. Aufgrund der großen Empfindlichkeit der Sensoren, könnte beispielsweise der Fall eintreten, daß bei einem unbelasteten Trittbrett bei schneller Fahrt durch ein Schlagloch kurzzeitig eine vertikale nach unten gerichtete Kraft detektiert wird, die zu einer Drosselung der Geschwindigkeit führen würde. Insofern kann es zweckmäßig sein, eventuell in Abhängigkeit von den Fahrzeugparametern Zeitfenster vorzusehen, in denen die Signale der Sensoren ausgewertet bzw. auch nicht ausgewertet werden.The control device is preferably also for recording and processing the vehicle data. For example, the vehicle speed in the Evaluation of the measurement signals from the sensors are included. Due to the high sensitivity of the sensors, for example the case could occur that with an unloaded running board when driving fast through a pothole a vertical downward force that is too short is detected would reduce the speed. So it can be appropriate, possibly depending on the vehicle parameters To provide time windows in which the signals from the sensors are evaluated or also not be evaluated.

In der Fig. 2a ist ein solches Trittbrett 1 mit den dazugehörigen Haltemitteln 10 und 17 perspektivisch dargestellt. Das Trittbrett 1 weist einen L-förmigen Grundkörper auf, der um die horizontale Achse 16 am Trittbrettarm 10 schwenkbar gelagert ist. Das Trittbrett 1 kann somit aus der in den Fign. 2a und 2b gezeigten Arbeitsstellung in eine Ruhestellung hochgeklappt werden.Such a running board 1 with the associated holding means is shown in FIG. 2a 10 and 17 shown in perspective. The footboard 1 has an L-shaped Base body on the horizontal axis 16 on the footboard arm 10th is pivotally mounted. The footboard 1 can thus from the in Figs. 2a and 2b shown working position can be folded up into a rest position.

Das Trittbrett 1 ist über Haltemittel am Fahrzeug (nicht dargestellt) befestigt, wobei die Haltemittel einen rechteckigen Trittbrettarm 10 und ein Befestigungsblech 17 umfassen.The footboard 1 is fastened to the vehicle (not shown) via holding means, wherein the holding means a rectangular footboard arm 10 and a Include mounting plate 17.

Der Trittbrettarm 10 ist mittels des Befestigungsbleches 17 starr am Fahrzeug befestigt, so daß sich Belastungen des Trittbrettes 1 in Form von Biegekräften am Trittbrettarm 10 bemerkbar machen. Wenn wie in der Fig. 2a eine Last FLast auf das Trittbrett einwirkt, entstehen am Trittbrettarm 10 Biegemomente, die zu einer Materialdehnung 11 des Trittbrettarms führen.The footboard arm 10 is rigidly fastened to the vehicle by means of the fastening plate 17, so that loads on the footboard 1 in the form of bending forces on the footboard arm 10 become noticeable. If a load F load acts on the footboard, as in FIG.

In der hier gezeigten Ausführungsform befindet sich in der Seitenfläche 12 eine Meßdosenöffnung 18, in die eine Sensoreinrichtung 20 eingesetzt ist.

Diese Dehnungsmeßstreifen sind jeweils paarweise gegenüberliegend angeordnet, wobei jeder Dehnungsmeßstreifen mit der Vertikalen einen Winkel von 45° einnimmt. Dadurch wird erreicht, daß sowohl vertikale als auch horizontale Kräfte von dem Dehnungsmeßstreifen 21a-d detektiert werden. Die paarweise Anordnung hat den Vorteil, daß eine gegenseitige Kompensation der Dehnungsmeßstreifen möglich ist, um auf diese Art und Weise Fehler auszuschließen.In the embodiment shown here, there is one in the side surface 12 Load cell opening 18 into which a sensor device 20 is inserted. The Sensor device 20 consists of a cylindrical base body on which a total of four strain gauges 21a-d are arranged. This Strain gauges are arranged opposite each other in pairs, each strain gauge with the vertical at an angle of 45 ° occupies. This ensures that both vertical and horizontal Forces from the strain gauge 21a-d are detected. The pair Arrangement has the advantage that mutual compensation of the Strain gauges are possible to avoid errors in this way excluded.

Die Dehnungsmeßstreifen 21a-d sind an eine nicht dargestellte Wheatstone'sche Brücke zur Auswertung der erfaßten Materialdehnungen angeschlossen. Die in den Fign. 2a bis 2c gezeigte Anordnung erfaßt Bewegungen des Trittbretts in vertikaler Richtung sowohl nach oben als auch nach unten und gegebenenfalls Torsionen, die sich ebenfalls in Längenänderungen oder Biegemomenten des Trittbrettarms 10 bemerkbar machen.The strain gauges 21a-d are on a Wheatstone, not shown Bridge for evaluating the recorded material strains connected. In the the fig. The arrangement shown in FIGS. 2a to 2c detects movements of the footboard in vertical direction both up and down and if necessary Torsions, which are also in changes in length or bending moments of the Make footboard arm 10 noticeable.

In der Fig. 3a ist eine weitere Ausführungsform dargestellt, die sich von der in den Fign. 2a bis 2c dargestellten Ausführungsform dadurch unterscheidet, daß anstelle von Dehnungsmeßstreifen im Bereich des Befestigungsbleches 17 Druckschalter 30,31 angeordnet sind und daß der Tragarm 10 in vertikaler Richtung verschieblich gelagert ist. Weitere Befestigungsmittel, wie Anschläge usw. werden der Übersichtlichkeit wegen weggelassen.A further embodiment is shown in FIG. 3a, which differs from that in FIG the fig. 2a to 2c shown embodiment differs in that instead of strain gauges in the area of the mounting plate 17 Pressure switches 30,31 are arranged and that the support arm 10 in vertical Direction is mounted. Other fasteners, such as stops etc. are omitted for clarity.

Der Druckschalter 30 ist in vertikaler Richtung angeordnet und liegt mit seiner Sensorspitze an der Unterseite 13 des Tragarms 10 an, so daß er bei einer Lasteinwirkung senkrecht nach unten betätigt wird. Hierzu ist der Trittbrettarm 10 mit mindestens zwei Freiheitsgraden in Richtung der Drehmomente und Querkräfte beweglich im Gelenk 19 gelagert, wie dies in der Fig. 3d dargestellt ist. Biegeelemente des Tragarms werden durch einen Druckschalter 31 erfaßt, der in horizontaler Richtung angeordnet ist und an der Rückseite 14 des Trittbrettarms anliegt.The pressure switch 30 is arranged in the vertical direction and lies with it Sensor tip on the underside 13 of the support arm 10, so that it at a Load is actuated vertically downwards. This is the footboard arm 10 with at least two degrees of freedom in the direction of the torques and Shear forces movably mounted in the joint 19, as shown in Fig. 3d is shown. Bending elements of the support arm are activated by a pressure switch 31 detected, which is arranged in the horizontal direction and on the rear 14th of the footboard arm.

In der Fig. 4 ist eine schematische Darstellung der gesamten Vorrichtung dargestellt, aus der die Verknüpfung der Belastungserkennungseinrichtung mit den Fahrzeugkomponenten dargestellt ist.4 is a schematic representation of the entire device shown from which the linkage of the load detection device with the vehicle components is shown.

Die beiden Trittbretter 1, 2 sind an eine Batterie, vorzugsweise an die Fahrzeugbatterie 7 angeschlossen. Über die elektrischen Verbindungsleitungen 8 und 9 sind die beiden Trittbretter 1 und 2 an die Steuereinrichtung 3 angeschlossen, die die von den Sensoren gelieferten Daten verarbeitet und in Signale für die Fahrzeugkomponenten umsetzt. Dementsprechend ist die Steuereinrichtung 3 über die Leitungen 50, 51 und 52 mit dem Getriebe 6 und dem Motor 5 verbunden. Diese Datenleitungen 50, 51, 52 sind auch dazu ausgebildet, Informationen über die Fahrzeugkomponenten 5 und 6 an die Steuereinrichtung 3 weiterzugeben, so daß diese bei der Auswertung der Sensorsignale berücksichtigt werden können. In der hier gezeigten Darstellung ist noch eine Anzeigeeinrichtung 4 zwischengeschaltet, die im Führerhaus des Fahrzeugs angeordnet ist und dem Fahrer die entsprechenden Informationen über die Belastung des oder der Trittbretter übermittelt.The two running boards 1, 2 are connected to a battery, preferably to the Vehicle battery 7 connected. Via the electrical connection lines 8 and 9 are the two running boards 1 and 2 to the control device 3 connected, which processes the data supplied by the sensors and in Converts signals for the vehicle components. Accordingly, the Control device 3 via lines 50, 51 and 52 with the gear 6 and connected to the engine 5. These data lines 50, 51, 52 are also for this trained, information about the vehicle components 5 and 6 to the Pass on control device 3 so that this when evaluating the Sensor signals can be taken into account. In the illustration shown here is still a display device 4 interposed, which is in the cab of the Vehicle is arranged and the driver the appropriate information transmitted about the load on the running board (s).
